Nye made a stop at the Florida Institute of Technology in support of President Barack Obama's reelection.

Hundreds of students stood in line to shake Nye's hand. When he talks, college students, who've grown up with his science-based TV show, listen. He's urging them to vote for Obama for the sake of science, including protecting the environment, the climate and exploring space.

"Where did we come from and are we alone? And to address those two questions as humans, we have to explore space," said Nye.

Nye said the president's plan is the right one because its the one that will eventually put humans on Mars.

"If we were to discover living things, as evidence rather, of living things on Mars it would completely change the world," said Nye.

Under Obama's plan, human exploration of Mars would not start until sometime in the 2030s. Private companies would start launching astronauts from the Cape in 2017, and NASA's gigantic super-rocket would not be ready till the 2020s.

Challenger Mitt Romney has accused the president of not having a serious space plan.

"It's time to have a mission of a space program of the United States of America," said Romney.

However, Romney has not advanced any space plan.

After a tour of Dynamic Systems, Controls and Mechatronics at FIT, Nye participated at a roundtable discussion.

Obama backers see Nye as someone who might make a difference in the big swing state of Florida.
